Purchased a new in box Acadia Nav unit and have a question regarding the voice recognition feature. I have the rse package btw. Will the voice recognition feature work after I replace the old stock with the new oem nav. I have seen some people have had to run a wire(s) from the nav unit to some sort of module, not sure what and where the module is though. Also regarding the back up camera, I looked where the tire jack is and I have the small silver (chrome) module there, is this where the wiring (plug) goes to for the camera? After pouring through many of the posts here I'm a little confused about the chrome module in the tire jack compartment. Any help would be appreciated. Probably will tackle the install next weekend and the camera in the future. I know that the dealer might have to "reprogram" the vehicle for the nav but do they have to do anything else regarding the backup camera, (flash the nav unit)? Just want to get some questions answered before I tackle this.
